I ride on a Kona Grand Prix SDG Saddle, I'm a big guy and as long as you have your seat fitting underneath your properly it's comfy...the first few rides after not being on a while will most likely kill you though

I've actually been looking into one myself... Mine has a Body Geometry Sport, which isn't TOO bad but I'd rather have one of the nicer ones that comes in varying widths so it will fit my ass better. The Fizik Arione is nice, but looks to be a bit too expensive for my tastes.

Also, you have to look at how much you're willing to spend..the higher end Specialized BG saddles and the Fiziks are well over $100... The nice thing about the Arione and Gobi is that they have the "slats" cut into the shell to allow them to break in and conform to your butt. They've gotten rave reviews, but they're not cheap. Definitely a bit out of my price range.

It is worth it to spend more money on a saddle to get the one that is most comfortable. The saddle is where you are going to have the most contact with the bike so you want it to be as comfortable as possible. The saddle is the one component you should not compromise on.
